A Wakefield man was ordered held in lieu of $100,000 bail and sent down to Bridgewater for evaluation at his arraignment today on a variety of charges related to the alleged act of performance art that led police to shut Boylston Street for more than two hours last night[3] on the anniversary of the Marathon bombings.

Kevin "Kayvon" Edson was charged with disturbing the peace, disorderly conduct, disturbing a public assembly, possession or use of a hoax device and making a false bomb threat, the Suffolk County District Attorney's office reports The latter two charges carry up to five and up to 20 years in state prison upon conviction, the DA's office says.

Police shut Boylston Street at the Marathon finish line just a few hours after memorial services on the street and as two brothers who survived last year's bombing approached the finish line after a walk from Hopkinton - after their encounter with Edson there. The entire Green Line was shut down at one point as the bomb squad blew up his backpack and another backpack found at the scene (Police report[4] that backpack belonged to "a local media outlet").

According to the DA's office:

Wearing black clothing and what appeared to be a veil covering his face, Edson removed his shoes and began walking toward the finish line from the direction of Trinity Church. He was yelling and wearing a black backpack.

Alerted to this behavior and aware that the bombs that killed three and injured scores more last year had also been transported in black backpacks, Boston Police approached Edson and asked what was in the bag. Edson allegedly told them it contained "a rice cooker." The officers were mindful that the Marathon bombs are believed to have been constructed with pressure cookers.

Through an opening in the top of the backpack, officers at the scene could see it contained some kind of device. Officers instructed him to remove it and the Boston Police Bomb Squad was called to the scene. At about that time, additional officers began clearing civilians from the scene, bus and subway service was suspended in the immediate area, and Edson was brought to the nearby Boston Public Library for a brief interview.

In a post-Miranda statement to Boston Police and federal agents, Edson allegedly acknowledged knowing what he was doing and said "it was being conceived in my head." He allegedly explained his actions as "symbolism" and said "the performance got the best of me." Beneath his veil, his face was streaked with blue and yellow paint.
